MPW Makefile Conversion - mpw - Applefritter: Git

MPW's make utility is similar to the Unix make utility. Similar enough that some makefiles can be converted with simple text replacements.

Here is an MPW makefile from IR 2.0.2 (ir.make):

IR ƒƒ IR.make ∂
		IRInit.aii.obj ∂
		RequestProc.aii.obj ∂
		IR.rfork
	LinkIIGS -t $B6 -at $0000 ∂
		IRInit.aii.obj ∂
		RequestProc.aii.obj ∂
		-o IR
		DuplicateIIgs -y -m IR :

IRInit.aii.obj ƒ IR.make IRInit.aii
	AsmIIGS -t IRInit.aii
RequestProc.aii.obj ƒ IR.make RequestProc.aii
	AsmIIGS -t RequestProc.aii
IR.rfork ƒ IR.make IR.r 
	RezIIgs IR.r -o IR.rfork
	Duplicate -r -y IR.rfork IR

ƒƒ and ƒ should be replaced with :.
∂ should be replaced with \.
$ needs to be escaped as \$$.
mpw commands (AsmIIgs, LinkIIgs, RezIIgs, and Duplicate) are executed as mpw command (unless you generate shell scripts for each command).
the DuplicateIIgs command is no longer necessary.
if the makefile (IR.make) is included as a dependency, it should be updated to the new name.

The modern makefile (makefile) is now:

IR : makefile \
		IRInit.aii.obj \
		RequestProc.aii.obj \
		IR.rfork
	mpw LinkIIGS -t \$$B6 -at \$$0000 \
		IRInit.aii.obj \
		RequestProc.aii.obj \
		-o IR
    mpw Duplicate -r -y IR.rfork IR

IRInit.aii.obj : IR.make IRInit.aii
	mpw AsmIIGS -t IRInit.aii
RequestProc.aii.obj : IR.make RequestProc.aii
	mpw AsmIIGS -t RequestProc.aii
IR.rfork : IR.make IR.r 
	mpw RezIIgs IR.r -o IR.rfork

(the Duplicate command was also moved from IR.rfork to IR since I prefer to set the resource fork after linking).

More complicated makefiles involving variables require more work and editing.
